Serb Djokovic, 31, said: “I don’t like to involve myself in any political exchange or situations. And it’s unfortunate that we are both drawn into this right now.

“Right now we just don’t have obviously enough information, and we have to look into that a bit more and then we’ll make our decision soon.”

World number one Nadal added: “Of course I’m aware of all the situation. But I had a commitment since one year ago to play there. And my team is talking to them, to analyse the things. That’s it.

“It’s terrible that one journalist lost his life. I know something happened very bad inside there. So we are looking about how evolves the situation and I hope the things will clarify as soon as possible.”
